Upfront cost — no obligation An annual boiler service is the single best way to avoid an unexpected breakdown, keep your energy bills down, and protect the manufacturer’s warranty — most warranties require a yearly service to stay valid. Gas First carries out thorough boiler services across East London and Essex, checking that your boiler is burning safely, running efficiently, and free of the early warning signs that lead to winter breakdowns. It’s a small, planned cost that prevents far larger ones.
Helpful reading: How often should you service your boiler?
What does a proper boiler service actually check and include?
A proper service is more than a quick glance. Our engineer inspects and tests the key components — the burner, heat exchanger, controls and safety devices — checks the gas pressure and flow, examines the flue and combustion to confirm it’s burning cleanly and safely, looks for corrosion or leaks, and confirms the boiler meets manufacturer and safety standards. We finish by letting you know of anything that needs attention before it becomes a problem.
Do I really need to service my boiler every year?
Servicing protects three things: your safety (a poorly maintained gas appliance can produce carbon monoxide), your money (a well-tuned boiler runs more efficiently and lasts longer), and your warranty (most manufacturers void cover without proof of annual servicing). Booking the same time each year — many people choose late summer or early autumn, before the heating season — keeps it simple.

Landlord with rented properties? Here's what you need to know about boiler servicing.
If you let a property, a boiler service is separate from your legal Gas Safety Certificate (CP12) — but both are best done together. We can service the boiler and carry out the annual gas safety check in one visit, saving you time and a second call-out. See our Landlord Gas Safety Certificate page for the legal requirements.

When's the best time of year to book a boiler service?
Give us your postcode and preferred day and we’ll arrange a convenient slot. A standard service is quick and tidy, and you’ll get a clear summary of the boiler’s condition afterwards. If we spot anything that needs repair, we’ll explain it and the cost before doing any extra work.
Frequently Asked Questions
How often should I service my boiler?
Once a year. Annual servicing keeps the boiler safe and efficient and is usually required to keep the manufacturer's warranty valid.
How long does a boiler service take?
A standard service is typically completed within an hour, depending on the boiler and its condition.
Will a service keep my warranty valid?
In most cases yes — manufacturers generally require proof of an annual service by a Gas Safe registered engineer. We provide a record of the service.
Can you service and do my landlord gas certificate together?
Yes, we can combine an annual boiler service with a Landlord Gas Safety Certificate (CP12) in a single visit.
When is the best time of year to book?
Late summer or early autumn is ideal — your boiler is checked and ready before the cold weather puts it under load.
What paperwork do I get when my boiler is serviced?
You will receive a service report listing what was checked, any faults found and any parts replaced. If we also carry out a gas safety inspection at the same time, you will receive the gas safety certificate too.
What happens if I do not service my boiler every year?
Skipping the annual service tends to mean lower efficiency, a higher chance of breakdowns and potential safety issues. Many manufacturers also require an annual service to keep the warranty valid. Regular servicing helps your boiler run safely and last longer.
Is annual boiler servicing a legal requirement?
For homeowners there is no law requiring it, but it is strongly recommended and is often a warranty condition. Landlords are not required to service a boiler annually, but they must keep it safe and in line with manufacturer requirements, so an annual service is the practical way to meet that duty.
What is the difference between a boiler service and an inspection?
An inspection is mainly a visual and operational check. A service goes further by cleaning key components, checking gas pressure and efficiency, and testing for faults, so it is the more thorough of the two.
What does a combi boiler service include?
A typical combi boiler service covers the main components and controls, flue and ventilation checks, gas pressure testing, condensate trap and filter cleaning, and leak and fault testing, followed by a written report.
How much does a boiler service cost in East London?
A standard annual boiler service starts from £79. The exact price depends on the boiler type and condition, and we confirm the cost before we begin, with no obligation. An annual service is one of the cheapest ways to avoid an expensive winter breakdown and to keep your manufacturer's warranty valid.
